Abstract: Medical devices for cutting and suturing biological tissue generally include a shaft and first and second guide members each including a first portion coupled to the shaft at a first location and a second portion coupled to the shaft at a second location. The first portions are movable along the shaft relative to the second portions, and the first and second guide members define an arcuate profile and are configured to flex in response to such movement. When used to cut tissue, the medical device may further include a blade positioned between the first and second guide members. When used to suture tissue, one or more suture guides may be provided on the first guide member for directing a suture needle through tissue proximate the first guide member. Methods of repairing and replacing a meniscus using the medical devices are also provided.
